Generic Servo Rant

Hey guys,

I generally don't hang out in the pattern forum as I'm a GS 3D & IMAC flier, however I need your guys' honest opinion... I'm looking for some GOOD servos to basically switch my fleet over to. As we all know, over the years we all become pickier and pickier generally and want better performing equipment as we progress. My rant is that it almost seems impossible to buy a GREAT high quality servo that isn't nearly $200 a piece now a days. Now I've had a lot of success with cheap servos, mid-line servos and even hobbyking stuff on cheap small planes over the years, but for IMAC on the big gassers, I want something that is locked in. It seems like every single servo sub $125 these days has major "backlash" (though I would call it slop as there's no need to have this extreme excessive backlash for temp expansion...) or poor centering under load these days...

I'm not trying to slam any brands here, but man, over the years I've found the JR 8711's & 8911's to be brutal for "backlash", even brand new out of the box. I've tried and seen so many other brands brand new first hand and thought to myself "well that's another one I wont buy". I find most of the Savox line (which I was totally sold on until I started seeing how much slop the HV and "high end" of their line had) sloppy too.

Why can no one make a TIGHT gear-train servo sub $100ea these days besides Futaba? (Ie. 9157's I use and LOVE except they're not HV, brushless or titanium, and way over $100ea). Ive seen many in their lineup that are amazing for minimal gear lash which is good. Hitec (basically only the 7955TG servo seems great from their lineup from what I've tried but could be others like the 7954, though Hitec is generally not known for awesome centering for pattern competition), MKS & BK servos (but these are both $$$).


Since you pattern guys know TIGHT, ACCURATE centering better than anyone in the business, what do you guys recommend as a GREAT centering, MINIMAL to almost non-existant backlash, LONG LASTING gear train servo (preferrably titanium for gasser vibs), HIGH torque (400oz+), descent speed (.12 or faster) and preferably HV? I always prefer Titanium Nitride coated gear trains over steel, but I'm finding that may just be brand & model specific.


Thanks guys, and sorry for the rant. I'm just sick of all the sloppy servos that keep coming out over the years. Any recommendations?


Thanks guys.

Take a look at the MKS777. I think it is everything you have described. Tightest gear train I have seen and it retains it overtime.

HV
Speed 0.1
Torque 520oz
Titanium gears

...........and $106.99

Cool, thanks Joe Smith! I was going to look into those as I couldn't believe the quality of the other MKS servos in my hands recently... Thanks a lot!

I see the MKS HV1220 also look great at a little less torque of 320oz, BUT their only 57g each instead of 80g like the 777! That would be very nice and one thing I really like about the Savox 1256TG's currently in one of my birds is their light weight for the performance.

Edit: The DS1230's also look great at 337oz/0.11 for LiFe as I'm still running A123's in most of my planes if I dont switch them over.

To get equal stats though the prices are similar for me. I prefer Brushless High Voltage and those are still up where my Futaba servos are price wise. BLS172 or 177 for example for Futaba and the HBL860 for MKS. All in the $200 ballpark.

Does anyone know anything about these servos advertised here in the FG forum?

That's not accurate

2270
.12 at 444 ounce

1270
.11 at 484 ounces

1230
.16 at 500 at 6 volt

2230
.13 at 583 at HV

These servos are nice and I would have no problem suggestion any of these servos. I have tested all of them

A buddy of mine tried a set. They were great at first but got sloppy fairly quickly.

BTW I'm a big fan savox servos and of Brian.

we see so many 450+ torque figures these days but if you go 4-5 years back, people were successfully using 350ish torque servos in 35% and bigger planes....

the only servo in my experience so far that can be called bulletproof is a 7955TG........i use it in most of my planes and rc cars as well........years of bashing and no slop none whatsoever........

Not to hijack the thread, but do the smaller MKS's have the same accurate geartrain? I'm outfitting a 71" slick - 777's would be major overkill.

Thanks,

Matt
